What size wheel spacer would I need to run on a 98 3500 4x4 daully to fit 265 75 R16 tires?

 

anyone know?

I have been told I need a wheel adapter for 400.

 

I got it figured out

 

I don't know, but be sure and use a spacer. I put 235/75R16's on my 99 without spacers and what resulted was the rears polished each other on the insides and the fronts rubbed on the body at full lock either direction. Have been told 235/85's would fit without spacers.

Cheers,
